VISE.

SPECIFICATION forming part of Letters Patent No. 699,585, dated May 6, 1902. Application filed April 5, 1901- Serial No. 54,435. (No model.)

10 all whom it may concern.-

Be it known that 1, WILLIAM E. SNEDIKER, a citizen of the United States, residing at the corner of Ninth and Market streets, Camden, in thecounty of Camden and State of New Jersey, have invented certain new and useful Improvements in Vises, of which the following is a specification.

My invention relates to improvements in Vises, andparticularly to that class of vises known as the bench-vise, having a fixed arm and a movable arm, pivoted together at their lower ends and held in position by a link, through which said arms pass, and the arms being provided at their uppet ends withjaws.

The object of my invention is to improve certain details of the vise, which will render it more useful and facilitate the operation of the same.

Referring to the drawings, Figure 1 represents a vise embodying my improvements. Fig. 2 is a perspective view of a portion of the vise. Fig. 3 is a partial sectional view showing the arms expanded. Fig. 4 is a detached perspectiveview of the bolt and staple. Fig. 5 isa detached perspective view of the details of the adjustable jaw-face.

In the drawings, A represents the fixed arm of the vise, having the jaw a and at its lower end a post a, which rests on the floor, and a projection a by which the vise is secured to a bench. On the arm A is a hearing a carrying a pin a", on which is pivoted the movable arm B, carrying the jaw b.

O represents a link or sling. (More clearly shown in Fig. 2.) At one endis asolid portion which acts as a nut and carries the adjusting-screw c. The side plates 0 c encircle the arms A andB and are connected at the back ends by a bolt D, which engages with a rack E on the arm A. The arm 0 is held in position by the lugs b and b on the arm B. The end of the link carrying the bolt D rests on the rack E by its own weight and is also held down by the spring F, which acts against the under side of thelink at the front end. The pin b acts as a fulcrum, the result being to force the back end of the link down and hold it in engagement with the rack E. The jaws of the vise can be quickly opened by lifting the back end'of the link out of engagement with the rack E, and the arm B will swing open by the action of the spring G, which is attached to a lug g on the fixed arm A and to a pin g, carried by the arm B, which is placed below the fulcrum a, thereby gaining a greaterleverage than by placing it, as heretofore, immediately above the fulcru in, and also overcoming the difficulty experienced from the dirt collecting on top of the spring, which would prevent the movable arm from operating properly.

The bolt D, which is carried by the link 0, is formed from around bolt. The middle portion which comes in contact with the rack is flattened, so as to form a right angle, as shown in Fig. 4E. The bolt D passes through openings in the side plates 0 c of the link 0 and turns loosely therein, so that it may adjust itself to the teeth of the rack E. The head of the bolt is provided with a recess d, and a pin 0 is placed on the side plate of the link 0, so as to engage with the head of the bolt'and prevent said bolt from turning too far either way. The bolt is held in the link by the key H, which fits over the end of the bolt, an annular groove it being provided to receive said key.

In a vise of this character it is desirable to have the faces of the jaws parallel, and to do this it is necessary to have one of said jaws adjustable, so that it will adapt itself to the surface of the article to be clamped in the Vise. In Figs. 3 and 5 is shown my improved method of securing the adjustable jaw-face b to the jaw b. The jaw-face b extends the full width of the jaw 12 and has on one side a curved surface which fits in a correspondingly-shaped groove in the jaw 12. On the jawface I) are provided lugs 19 in which is secured a bar I). A clamp 11 is secured to the arm B by the set-screw b On this clamp is provided a curved portion I), over which passes the bar If carried by the jaw-face Z), as shown in Fig. 3. A recess 12 is provided in the jaw b to allow the lugs b to turn freely. It will readily be seen that by this construction the jaw-face b can turn freely to adjust itself to the work and is held firmly in place by the clamp 11 The parts are entirely concealed and protected, which is a great advantage over the forms heretofore used.

On the arms A and B are provided pipegrips I and J. The grip J is rigidly secured Ion to the arm B by pinsj, as shown in Fig. 3. The grip I is adjustably secured to the arm A by a pin 1, which passes through openings in lugs carried by the grip Iand the lug 7; on the arm A. This allows the adjustable grip to adapt itself to the article desired to be clamped.

Having thus described my invention, I claim and desire to secure by Letters Patcut- 1. In a vise and in combination with jaws carried by fixed and movable arms and a link incasing said arms, of a bolt having surfaces forming a right angle adapted to engage with a rack on said fixed arm, a key for holding said bolt in position, a bolt-head having a segmental recess and a pin carried by said link engaging With said bolt-head substantially as described.

2. In a vise and in combination with jaws carried by fixed and movable arms and a link incasing said arms, of lugs on the movable arm above and below said link, a spring secured to said movable arm tending to force the back end of the link down, and. a spring placed below the fulcrum of the movable lever tending to keep the jaws separated, substantially as described.

3. In a Vise and in combination with jaws carried by fixed and movable arms pivoted together at their lower ends, of an adjustable jaw-face having lugs carrying a rod, a clamp secured to said movable arm, aprojection on said clamp curved to fit the surface of the adjustable jaw-face and adapted to hold said jaw-face in place and allow it to turn freely, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.
